Alpine Security Threat Detection
Mid-market and enterprise security teams with mature EDR deployments should pick Alpine Security Threat Detection when you need active hunting that actually correlates across your existing tools instead of running parallel to them. The service covers DE.AE and RS.AN functions at the NIST level, meaning they're built to find what your EDR misses and move quickly into forensics, not just flag alerts for your team to triage. Skip this if you're looking for a standalone platform or need heavy automation; this is a managed hunting service that assumes you already have security infrastructure in place and want humans who know how to exploit EDR data for detection.
Threat hunters and SOC analysts who need to operationalize custom detection logic without licensing costs should adopt YARA Rules for ProcFilter; the tool translates portable YARA signatures into native ProcFilter rules, letting you reuse threat intelligence from open sources and internal research immediately. With 90 GitHub stars and free licensing, it removes the friction of building process-monitoring detections from scratch. Skip this if your team lacks the YARA expertise to write or adapt signatures, or if you need a turnkey rules engine rather than a framework for building your own.
